When reading a resume what red flags do recruiters look out for?

Recruiters approach resumes as risk-mitigation documents. Because hiring is expensive and time-consuming, they scan for signals that a candidate might be unreliable, stagnant, or lacking in impact. They often spend less than ten seconds on an initial screen, looking for reasons to move a candidate to the "no" pile.

One primary red flag is frequent job-hopping—multiple roles lasting less than 18 months without a clear upward trajectory. This suggests a low return on investment for the company. Similarly, vague descriptions that focus on duties rather than results (e.g., "Responsible for sales" versus "Exceeded sales targets by 15%") signal a lack of ownership or performance.

Unexplained employment gaps are another common concern. While gaps are common for health or family, silence on the page allows recruiters to assume the worst, such as a performance-related firing. Finally, attention to detail is a proxy for your professional standard. Typos or inconsistent formatting suggest that if you aren’t diligent with your own self-promotion, you likely won’t be diligent with company projects.

Recruiters are looking for a cohesive narrative; anything that breaks that story—like a sudden pivot to a lower-level role—requires a proactive explanation.

Are you worried about a specific part of your own work history, such as a long gap or a series of short-term roles?
